Brooks离子阱质谱仪

The 835 VQM is a mass spectrometer that operates from UHV to 10^-5 Torr and accurately measures the gases in the vacuum chamber. The 835 VQM Differential Pump System delivers the advantages of the 835 VQM at higher pressures. The VQM system consists of an autoresonant ion trap mass spectrometer gauge, a VQM Controller and VQM Viewer software that that converts raw data into actionable information. The system is ratiometric, meaning that it determines the ratio of each gas to other gases in a vacuum chamber. It is usually coupled with a total pressure gauge to provide partial pressures of each gas as indication of the quality of the vacuum in the chamber.

Key Features

• 1?145 amu total and partial pressure measurement information in 85 ms, or 1?300 amu in 125 ms
• Instant access to critical measurement information including the 10 most prevalent gases in normalized, percentage and absolute values as well as total pressure and partial pressure trend graphs
• Accurate hydrogen and helium measurement (no zero blast)
• Data logging at all sample rates
• Easy single-gas calibration using a gas already in your vacuum system
• Low power (only 15 watts)
• Compact design and remotely mounted gauge using a cable from one to 20 meters long
